I’ve found rust generally to be far more writing than all other languages I’ve used

Swift: : Equatable

(assuming all the members of the struct are themselves equatable, if not the compiler will tell you to implement the == method)

in which “other languages” is it so very hard?

On behalf of Java developers everywhere - thank you Project Lombok!

In Clojure equality checks are done by value as the default, and all the data is represented using a set of common data structures.

Implementing Equality in Haskell:

deriving (Eq, Ord)

I’d argue that the reason this is so bad in other languages is because of horrible default implementations.

Look at tostring in java, getting a somewhat printable object would be easy if the […]

Now explain PartialEq, and why it’s mandatory.

I’m much more impressed by the fact that a type can implement PartialEq and not Eq. Now that’s nice design!

I mean, if your IDE does it for you, is it really that much better that it’s shorter?
